Elite is the go to place in the Pittsburgh for running shoes. Their staff is always friendly and inviting and they go that 'extra mile' to ensure that you are in the proper shoes for your gait.
I started shopping at Elite when I was a Middle School Runner and despite the 45 minute trip there, it was always worth the drive. Now, 10+ years later, whenever I return home to the region, Elite is always on my list of places to go. It should be on yours too!
